Performed a first floor dryer vent cleaning and removed a birds nest. Dryer vent, duct, flex hose and lint trap are all clear of lint and debris at this time. Dryer is functioning properly at this time and exhaust flow is optimal. Recommend dryer vent cleaning every 1-2 years. Installed new bird guard. Bird guard is firmly in place and will prevent another nest in the future. Thank you for your business!
